You can definitely generate more heat in the left rear if you increase the angle of the left rear trailing arm. I was in your same situation a few weeks ago, and during a test session spent a lot of time trying to develop more heat in the left rear tire. I kept increasing the cross weight, which did help, but once I increased the angle of the trailing, it really increased the heat in the left rear tire. I have also recently tried a J-bar mounted on the left side going over the pinion, and that also increased the heat in the left rear tire and made the temperatures more even. It also really hooked up the car on the slick track. Just a few things for thought, but don't be afraid to raise the left trailing arm chassis mount position up. Mine was in the 15-18 degree angle, and worked just fine.

Chad, do you run a rubber j-bar or solid?I run a rubber,bottom hole on the rear end,top on the frame.I found raising the left trail arm up too makes a big difference.I went to a 150 r/r spring(200 left).This weekend,if it stays smooth ,I might go to a 125.What rates do you run?

Hey Fred, you know what I run. I based my answer on the long panhard bar that I have been running, but I am curious to try the rubber cushioned J-bar. I felt your tires when you came off the track after the B-Main in Hanford and was impressed to notice the tires had uniform heat. I definitely think the J-bar is a very easy way to even out the tire temps across the rear, but I'm wondering why more chassis builders don't incorporate one into their new designs. I have had numerous personal conversations with Jammin and he is a firm believer on the long bars mounted behind. Just a thought to leave by.

I'm from Visalia, and run primarily at Kings Speedway in Hanford. Fred and myself are friends from Watsonville Speedway where we started racing street stocks. I understand you are from Antioch. It's been quite a while since I ran there, probably over 3-4 years when the track was still Nascar and ran it in my street stock. Lots of fun, but I won't be able to go back until you guys switch to the American Racer tires. Too much money to buy those sprint car tires, and I've seen how much faster the modifieds are on your tires at Chowchilla before they instituted the tire rule. I'm #54, stop buy and say hi if you make it to any of the races in the valley.
